DEALCOHOLIZIN G- LIQUIDS.

Specification of Letters Patent.

Pat outed Mar. '10, 191:4.

Application filed January 10, 1911. Serial No. 601,866.

to it known that I ()r'ro (,lnnuanirr (linusror Lunwic Josnrrt Ovrnuucek, a aubject oi the King; of Great Britain, reaidiue at treat (trims rv, in the county of Lincoln, l lngg lantl, have invented new and useful linprovernents in Dealcolwlizino; Liquids, o't \Vlllt'll the following in a specification.

The object, of the present invention is to d i-alcoholize various liquids without suhinittin thrin to a hoiling process and without; the employment ot a vacuum pan.

By means oti no, invention liquida may he de-ah'oholized and the alcohol may or may not he collected. l Vhether or not, the alcohol is collected depends to home extent upon the nature ot' the liquid under treatment. Thus when heer is treated the object is to obtain a inuraleoholie beverage and the alcohol generally Speaking will he run to waste. hot when distiller-s wort is treated the alrohol will he eollectet'l.

According to the present invention I place the liquid to he treated in a nuuilrer of closed tanks. pt'el'erahly of \arious heights. the hottolns being; arranged one slightly below the hottom of a. next. adjacent tank. acid gaa at a preasure o't aho'ut pounds per square inch is caused to enter the lower part. of the tirst tank, it passes up through the liquid in the lower part of that tank and escape; at the upper part of the tank. It is then eoi'idncted to the lower part of the second tank and passes up through the liquid. ".lhe :arhonic acid gas thus; passes up through all the tanks and blows all or nearly all the liquid into froth. Means are pro- 'Vidcd for aaeertaining; the height of the l'roth in the last vessel so that. it may be prevented :t'rom passing out of the tanks. The carlmnic acid gas, after it has left the last tank, passea through a cooling coil and then into the water contained in the lower part of a gasometer and rises through the water into the upper part of the nanometer, whence it is canned to pass through coils where it warmed previous to again entering the first tank. The. process is thus; a continuous one,

the gas being need time :rtter time. until the required amount of or all alcohol removed from the liquid.

Nheu treating distillers wort the liquid is armed to ahout 90 F. in an atmosphere of carbonic acid and I then commence to pass the gas through it. The heating is continued until. the temperature reaches Carbonic alaud .li't) i During the whole oi llllS time th gas contiuursto pass through the liquid. lit'tl' however is not raised hovond 120 i in the itt't't)ltl1)tlll .lll if drawings i have shown apparatus suitable for carrying out the prore-.

vFigure 'l is a aide elevation of the complrte apparatus. some parts heing shown in i n and .wUlllU heing' hrokeu away. Fig. 2 i.-- a vertical section taken on the line '2 of Fig. l, and Fig. I) a plan. parts being lu'okeu away. of the chamher in which are arranged the tanks to contain the liquid to he treatet'l.

1/. and a. are the upper and lower parts of a gasomet'er. 'lhe tank o" is nearly tilled with water and the hell 1/. contains car 'ionie acid.

b is a pipe the upper end ol. which rises Il a): the level oi the water. The pipe I prunes, through the side oi the tank a and communi ates with coils e in which the gas is heated hy the strain coils I! located he neath the coils n. it being understood that the steam coils (l heat the liquid in the tank 9;. and the gas iu the pipe e is heated directly hy the heated liquid surrounding these pipes. In Fig. 3 only some of the coils are shown to prevent ((uii usion hut they are fully shown in Fig. i.

From the coils the gas pauses up the pipe 0 through one side of the first tank 7 down the pipe (3 in said tank. At its; lower end the pipe 0 is bent into a horizontal po sition and is provided with pertoratit'nis. It thus become; a rake or roueer which is marked 0'. The gas hlows through the liquid and finally escapes througirthe ipe r/ leading from the upper part of one tank to the upper partof the next tank 7. This; tank contains another pipe 0' and another rake or, rouser All the tank; f" f f f f each contain a pipe (1 and rake. or rouaer e and they are each connected to the next. tank by a pipe The gas finally paases through the pipe g provided with a cock into the coolingcoil 71 located in a casing 71.; From the coil 71. the gas passes through a pipe it into a pump i in the casing i and escapes from the pump through the pipe provided with the'two-way cock j. The pipe j enters the an]; a and is formed into a coil 7''- provided with perforations through which the escapes into the water. The course of the gas is clearlyindicated in Fig.

l by means ol. the arrows which are nuns bered consecutively l to 40, following the path of the gas.

Directly below the cooling coil hand connected therewith is a tank is provided with a cock /c. If the casing IL is packed with iceft h'e alcohol willdrip into the tank is when the cock is is open. If this latter be closed and the casing It be filled with water only the alcohol will pass' with the gas through the pump and be retained in the water in thetank a, whichlatter may be provided with a water inlet a and an overflow a". both of which, if left open, will cause the alcohol to flow away with the water.

The tanks 7'', f 7", f, 7*", are each provided with a sloping bottoz'n-nnd they are 7 all connected by cocks Z with an inclined pipe Z. The tank f provided with a sight gage to indicate the level of the froth in this tank.

m indicates; the level (it the liquid to be treated. This gradually passes with thegas in a condition of froth toward the tank f By means of the cocks Z and inclined pipe Z the liquid is allowed to pass back into the longer tanks.

The tanks f, 7, f 1, F, are located in a water tank it having gas-tight cover n. Each tank 7, ,F, f, f, has a cover 0 whi h: is held in close contact with its tank by screws 0' passing throijigh the cover a. I

The pipe 0 has a branch 7') provided with a cock 7), which branch enters the space 0. This, Space is connected by a pipe 0" with the pipe /t llthe cock Fig.2, be open and it the cock 1 Fig. 1, be closed, the air in the space 0 will be removed and will pass away through the tu 'o-way'cock j which is i open to atmosphere for that purpose and 1S closed to the tililk a to prevent the Water .iping. 23y means the space 0 iillttl v. ith carlicni a id gas bot ore the processot' lc-altgihwliz-iiug is started.

bcwgemz The water tank n is'provided with a in anhole and cover 71 The pipe e" is fitted with a manometer'e What I claim is lrThe herein described process for dealcoholizing liquids, which consistsfirst in placing the liquid under apositive atmospheric pressure, then raising the tempera ture of the liquid to about 90 F., then blowing the liquid into froth by passing earbonic acid gas through the liquid in sufiicient quantities, then cooling the mixture of .gas and alcohol and finally mixture through a body of Water. l

2. The herein described process for dealcoholizing liquids, which consists first in placing the liquid under a slight and posi tive atmospheric pressure, then replacing with carbonic acid gas a'ny airwhich there may be in the receptacle containing the liquid. then raising. the temperature of the liquid to about 90 F., then blowing the liquid into froth by passing carbonic acid gas through the liquid in suflicient quantitics and continuing the same until the liquid has been de-alcoholized to the desired extent, thcn cooling the mixture of carbonic acid gas and alcohol and finally passingthe said mixture through a body of Water which absorbs the alcohol therein.

3. The herein described process for tie alcoholizingli uids, which consists in p1ac- 'ing the liquitiuinder. a positive atmospheric pressure, then raising thetemperature of the liquid to about 90 l .,and then blowing the liquid into truth .by passing carbonic acid through the liquid in sufiicient quantities. I

In witness whereof I have hereunto set my hand in the'prescnce of twowitnesses.
